sb-bsd-sockets:get-host-by-address under MacOS?


Hello,

I'm using SBCL 1.0.10 under MacOS 10.4.10 (Intel).  

When I run:
(sb-bsd-sockets:get-host-by-address #(129 24 244 1))

I get an error as follows:
Name service error in "getnameinfo": 5 (ai_family not supported)
   [Condition of type SB-BSD-SOCKETS:NAME-SERVICE-ERROR]

Am I doing something wrong?  The same code seems to work fine under SBCL 
1.0.3 on my Intel Linux machine.  Unfortunately, I do not have the latest 
SBCL on that Linux box :P

Thanks!,
Jim

Re: sb-bsd-sockets:get-host-by-address under MacOS?

I get the same error under SBCL 1.0.10/MacOS 10.4.10 (Intel) and I
don't get the error under SBCL 1.0.3/MacOS 10.4.10 (Intel).

I don't have a different OS to test right now so I can't tell if
1.0.10 works on other systems.

For grins, I downloaded SBCL 1.0.3 - 1.0.10.  I found the error I reported 
below happens with all versions 1.0.4 and above.

Many thanks to Chris for pointing out that 1.0.3 does what I expect.

Peering closely at header files, it turns out that struct sockaddr_in  
has an additional length field on Mac OS X that wants to be defined  
and filled (and the Linux manpages, but not the Darwin ones, say that  
error number 5 can also mean "incorrect length", duh).

Anyway, sbcl version 1.0.10.38 tells me that you are looking for  
summit.hpc.unm.edu.

Cheers,

Rudi

Thank you Rudi!  Yes, that IP should resolve to summit.hpc.unm.edu!

Closures as callbacks

Dear developers,

I found a very simple way to use callbacks in CFFI or in alien-lambda without
the performance and memory implications we discussed, at least for the case
that the callback doesn't call C again:

The callback given to C is just a delegator to a closure that is saved in a
the global variable *once-to-c-closure-callback*.

--------------------------------------------------------------------
(defvar *once-to-c-closure-callback* nil)

(defcallback delegating-callback :double ((x :double))
  ;; (callback-index :int))
  (funcall *once-to-c-closure-callback* x))

(defun closure-callback (func)
  (setq *once-to-c-closure-callback* func)
  (callback delegating-callback))
--------------------------------------------------------------------
Here's an example with a C function executing the callback:
--------------------------------------------------------------------
// Compile with CF=testc && gcc -fPIC -c $CF.c && gcc -shared -Wl,-soname,$CF.so -o $CF.so $CF.o

#include <stdio.h>

double execute_callback (void* callback, double x) {
  if (callback != NULL) {
    printf("callback: %ld\n", (long)callback);
    double (*callback1)();

In case the C code receives another callback and wants to call both of them
interchangingly, one would have to use the array solution as well.

ASDF-install on Windows gives error

I'm trying to use ASDF-install on the Windows XP version of SBCL like so:

(asdf-install:install 'clx)

Every time I try to install CLX, right after SBCL says that it is
going to install to site-systems, the following error comes up:

debugger invoked on a SIMPLE-ERROR:
  #<SB-IMPL::STRING-OUTPUT-STREAM {AC19949}> is closed.

Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL.

restarts (invokable by number or by possibly-abbreviated name):
  0: [ABORT] Exit debugger, returning to top level.

(SB-KERNEL:CLOSED-FLAME #<SB-IMPL::STRING-OUTPUT-STREAM {AC19949}>)
0]

The STRING-OUTPUT-STREAM number is always different, but the general
error is always the same.

Does anyone know what would cause this?

what is SBCL equivalent to lispworks (comm:open-tcp-stream "localhost" portnumber))

Hello everybody...
i'm quite newbie in CL and SBCL, I'd like to try FOIL library to
interact with .NET system. Library is written originally for Lispworks
and as it seems to me the only platform specific thing is the
connection to network socket (I hope at least :-)

what is SBCL equivalent to Lispworks
(comm:open-tcp-stream "localhost" portnumber))

I've just installed latest SBCL for windows via msi installer...

Thanks for any tip...

  
Best regards

Trying to asdf-install cells

I am trying to install Cells in SBCL 1.0.9. When I run 
(asdf-install:install 'cells) and choose "personal installation" it spits out 
a load of binary garbage followed by:

When I CTRL-D I get the following error:
